What is the answer for this problem? if f(x)=3x-1 and g(x)=x+2, find (f-g)(x) a. 3-2x b. 2x-1 c. 4x+1 d. 2x-3

This is a problem involving the subtraction of two functions f(x) and g(x):

if f(x)=3x-1 and g(x)=x+2, find (f-g)(x).  In other words, find:

  f(x)  = 3x-1 
-{g(x) -(x+2)

f(x) - g(x) = 3x - 1 - x - 2 = 2x - 3  (answer)
